APPARATUS FOR CENTRIFUGALLY TREATING MOLTEN MATERIAL.

SPECIFICATION forming part of Letters Patent N 0. 433,145, dated July29, 1890.

Application filed March 3, 1890.

To all whom it may concern:

Be it known that I, ORRIN B. PEOK, a citizen of the United States,residing at Chicago, Illinois, have invented certain new and usefulImprovements in Appa-ratus for Centrifugally Treating Molten Material,of which the following is a specification.

The object of this invention is to improve a centrifugal apparatus foruse in the treatment of molten materials; and it has more particularreference to the construction of the curbing that surroundsthereceiving-vessel, and to providing means for protecting its interior.

In the drawings, Figure 1 is an elevation, partly in section, of acentrifugal machine embodying my improvements; Fig. 2, a section of Fig.1 on line 2 2, looking in the direction of the arrows; Fig. 3, anoutline view of a portion of the curbing and lining shown in Fig. 2, andFig. 4 a perspective view of one section of the lining.

V is the receiving-vessel; A, the shaft for supporting and revolving thesame; B B, journal-bearings for supporting and maintaining the verticalposition of the shaft; E, the curbing surrounding the vessel; F F,plates forming the top and bottom of the curbing;-f f, flanges on suchplates; G, a plate forming the wall of the curbing; I, a lining orprotector for the interior of the curbing; J, a ring or shelf upon whichthe lining-I rests; *5, bolts for holding the lining in place; and t aring passing around the curbing, through which the bolts '5 extend.

The receiving-vessel V is surrounded by a strong curbing E, preferablyconstructed out of two cast-iron or other suitable plates F F,preferably provided with annular flanges ff. These two plates constitutethe top and bottom of the curbing, and are preferably held together bymeans of a sheet of boiler iron or steel riveted or otherwise secured tothe flanges f f. In this way the sides or wall of the curbing ispreferably as shown in Fig. 1. The curbing serves to catch and confinethe material that is treated in the receiving-vessel and discharged fromit. The material is discharged or thrown off from the receivingvessel ina molten condition; but water is Serial No. 342,440. (No model.)

sprayed on it from the pipe h or other convenient means, cooling andhardening it'and rendering its action upon the interior of .the curbingor wall very severe, rapidly wearing the curbing at the pointwhere itfirst strikes, and in this way the wall is soon cut or worn entirelythrough, thus rendering the curbing unfit for further use.

To afford a protector for the interior of the wall of the curbing, andto prevent it from being rapidly destroyed, I have provided a cast-ironor other suitable lining 1, preferably made in sections and placed on orover the illt erior of the wall of the curbing, and located in such amanner that as the material from the receiving-vessel is discharged itwill be thrown against the lining instead of the wall proper. In thisWay it will be seen that the lining I will be worn instead of the wall,and that when the protector-or lining is worn so that it is not fit forfurther use it may be removed and a new one put in its place. I prefer,as above stated, to make this lining in sections, and, as shown in thedrawings, I prefer to secure the sections in their place by means ofbolts t'that extend through the lin-' ing and curbing, with their endscarrying the nuts on the outer side of the curbing, so that they areeasy of access. I also prefer to provide a ring '6' around the outsideof the wall of the curbing at any suitable point for the bolts i to passthrough. The ring 2' is to facilitate the easy locating of thebolts 1,since, as I prefer to wrap the outside of the wall be tween the edges ofthe flanges f f with wire to secure the required strength, it would bequite a difficult matter to extend the boltsthrough the Wire wrapping ifthe ring 2" was not provided. 1

To assist in holding the sections of the lining in, place, I prefer toprovide a ring or shelf J, upon which their lower ends may rest. While Ihave shown this lining as only covering a portion of the interior of thecurbing of course it may be extended down as far as desired; and While Iprefer to make it in sections, asshown,'which facilitates its easy removal and renewal it may be made in larger pieces, or as will best suitthe operator, so long as it is arranged to protect the interior of thecurbing; and, as I have also shown, I prefer to make the varioussections of the lining so that their edges will lap to prevent the smallparticles thrown f rom the receivingvessel from being driven between theedges of the sections of the lining. This is a matter of choice, anddoes not very materially effect the utility of the lining; also, asshown in the drawings, I prefer to provide recesses in the inside of thelining at the point where the bolts that hold it in place are located,so that the heads of the bolts may set in them, so to speak, or becountersunk, leaving a comparatively level surface on the interior ofthe curbing and lining, so the material will not stick.

The lining may be made in various ways and held to place in variousways, as by keys, wedges, or recesses; but as the intention of myinvention is to afford a means for protecting the interior of thecurbing from severe injury or being rapidly worn out and destroyed bythe material discharged from the receiving-vessel, I do not wish to belimited to any particular form of constructing or securing suchprotector or lining.

I claim 1. In a centrifugal machine for the treatment of moltenmaterial, the combination of a revoluble receiving-vessel adapted toreceive the material to be treated, means for su pporting and revolvingthe vessel, a surrounding curbing for arresting the particles thrown offfrom the receiving-vessel, and a removable lining on the interior ofsuch curbing to prevent it from being rapidly worn out and destroyed bythe action of the discharging material from thereceiving-vessel,substantially as described.

2. Ina centrifugal machine for the treatment of molten material, thecombination of a revoluble receiving-vessel adapted to receive thematerial to be treated, means for supporting and revolving the vessel, asurrounding curbing for arresting the particles thrown off from thereceiving-vessel, and a lining composed of removable sections on theinterior of such curbing to prevent itfrom being rapidly worn out anddestroyed by the action of the discharging material from thereceiving-vessel, substantially as described.

3. In a centrifugal machine for the treatment of molten material, thecombination of a revoluble receiving-vessel adapted to receive thematerial to be treated, means for supporting and revolving the vessel, asurrounding curbing for arresting the particles thrown olf from thereceiving-vessel, and a lining composed of removable sections held toplace by means of bolts extending through the lining and curbing fromthe interior to the exterior, substantially as described.

4. In a centrifugal machine for the treatment of molten material, thecombination of a revoluble receiving-vessel adapted to receive thematerial to be treated, means for supporting and revolving the vessel, asurrounding curbing for arresting the particles thrown off from thereceiving-vessel, a covering or envelope or wire around the exterior ofthe curbing, a ring or band around the exterior of the curbing, aremovable lining on the interior of the curbing, and bolts to maintainthe lining in place, extending through it and the curbing and throughthe ring on the exterior of the curbing, substantially as described.

5. In a centrifugal machine for the treatment of molten material, thecombination of a revoluble recei ving-vessel adapted to receive thematerial to be treated, means for supporting and revolving the vessel, asurroundii'ig curbing for arresting the material thrown off from thereceiving-vessel, a removable lining on the interior of such curbing toprevent itfrom being rapidly worn out and destroyed by the action of thedischarging material from the receiving-vessel, having bolts extendingthrough such lining to hold it to place, and the lining having recesseson its interior to accommodate the heads of such bolts, therebyaffording a smooth interior surface to the lining, substantially asdescribed.
